Abstract

Abstract The first examples of rodlike donor–photosensitizer–acceptor arrays based on bis- 2, 6-di (quinolin-8-yl) pyridine Ru II complexes 1 a and 3 a for photoinduced electron transfer have been synthesized and investigated. The complexes are synthesized in a convergent manner and are isolated as linear, single isomers. Time-resolved absorption spectroscopy reveals long-lived, photoinduced charge-separated states (τ CSS (1 a)= 140 ns, τ CSS (3 ...
